Wierd Shutdown With Xp Sp2

I seem to have found a new 'feature' in service pack 2 beta for windows xp.

you know when you click start>turn off computer and the box comes up that looks like this:

and the screen around it goes to black and white?

well here is what seems to happen with SP2:

instead of black and white it just keeps going until it is pitch balck around teh turn off part. im not sure if this is intentional or a bug, but it sure was funny the first time i saw it. what do you guys think? a new SP2 'feature' or is it just a bug?
